Description

Continuous label paper punched scrap winding device and punched scrap winding method

[0001] The present invention relates to an apparatus for winding continuous label paper and a method for winding the scrap.

This application claims priority to Japanese Patent Application No. 2017-154396 for which it applied on August 9, 2017, and uses the content here.

A continuous label paper punched scrap winding device, after printing characters or pictures on the continuous label paper, the label substrate and the adhesive layer of the continuous label paper are punched into a predetermined shape, and the unnecessary punched scrap portion is peeled from the mount A device for winding the scrap on a winding shaft is known. The punched scrap from which the label base material and the adhesive layer of a predetermined shape are peeled off has difficulty in ensuring the intensity|strength, and may be cut|disconnected before reaching the scrap winding shaft.

Therefore, it is undesirable to apply strong tension to the punched scrap from peeling the punched scrap from the ground until it reaches the scrap winding shaft.

Here, the tension applied to the punched scrap varies according to the change in the diameter of the roll of the punched scrap wound around the scrap winding shaft if the torque of the scrap winding shaft is constant. In addition, the tension applied to the punched scrap changes by affecting the mechanical loss of the mechanical system or the torque fluctuation of the servo motor due to the acceleration of the winding speed. Therefore, there is a possibility that the punched scrap may be cut due to a change in tension during winding of the punched scrap.

Further, the punched scrap is punched into a predetermined shape. Therefore, when tension is applied in the conveying direction, the punched scrap has a property of contracting in the direction perpendicular to the tension direction (the width direction of the punched scrap). Here, when the predetermined shape is a circular shape or an irregular shape other than a rectangle, it is difficult for the amount of shrinkage of the punched scrap to be constant. For this reason, it is conceivable that the load is concentrated on a portion with a large amount of shrinkage of the punched scrap and ripples in a direction perpendicular to the direction of tension. In this state, when the tension of the punched scrap fluctuates, the punched scrap is easily cut.

In particular, if the section from when the punched scrap is peeled off from the ground until it reaches the scrap winding shaft (hereinafter referred to as a scrap path) is long, the amount of shrinkage in the width direction of the punched scrap increases and the location where the load is concentrated increases. Further, if the shrinkage amount in the width direction of the punched scrap is large, a large portion and a small portion are generated in the roll diameter of the wound punched scrap, and the punched scrap wound at the large roll diameter becomes high tension.

The punched scrap is easily cut in a location where the load is concentrated because of a large amount of shrinkage in the width direction of the punched scrap or in a location where a high tension is generated due to a large winding diameter of the scrap.

Among the continuous label paper punched scrap take-up devices, there is a device that pressurizes the outer periphery of the punched scrap wound around the scrap winding shaft to the scrap roll driving roller in order to suppress the cutting of the punched scrap. The scrap roll driving roller rotates synchronously with the conveying speed of continuous label paper.

The adhesive layer of the punched scrap is attached to the scrap winding shaft by pressurizing the outer periphery of the punched scrap to the scrap roll driving roller. In this state, the scrap winding shaft is driven and rotated, and the punched scrap is continuously wound in a roll shape. According to this continuous label paper punched scrap take-up device, it is possible to wind up the punched scrap without applying tension, and it is possible to suppress cutting of the punched scrap (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2000-355459

However, when the punched area of the continuous label paper (that is, the area of a predetermined shape) is large, the shape of the outer peripheral surface of the punched scrap wound around the scrap winding shaft is distorted. For this reason, according to the continuous label paper punched scrap winding device of Patent Document 1, the outer peripheral surface of the punched scrap is in a distorted state, and is pressed into contact with the scrap roll driving roller. Therefore, there is a possibility that vibration may occur in the punched scrap.

Here, in general, when the punched area of the continuous label paper is large, the area of the punched scrap is small. For this reason, it becomes easy to cut|disconnect a punched scrap by vibration, and this becomes an obstacle to speeding up the winding speed of a punched scrap.

Accordingly, the present invention provides a punched scrap winding device and a punched scrap winding method for continuous label paper capable of suppressing the cutting of the punched scrap and speeding up the winding speed of the punched scrap.

In order to solve the above problems, the continuous label paper punched scrap winding device, which is an aspect of the present invention, conveys the continuous label paper subjected to semi-punching processing, and a peeling roller that separates the punched product and the punched scrap adhering to the ground. A continuous label paper punched scrap winding device provided with a scrap winding shaft installed to be spaced apart from the peeling roller to wind the punched scrap in the form of a roll, and the scrap winding shaft moving in a direction spaced apart from the peeling roller a mechanism, a first detection unit installed in the conveyance path of the continuous label sheet, for detecting the conveyance amount of the continuous label sheet, a second detection unit for detecting one rotation of the scrap winding shaft, and the scrap winding shaft rotating once a calculation unit for obtaining the roll diameter of the punched scrap wound around the scrap winding shaft based on the detection results of the first detection unit and the second detection unit each time, based on the roll diameter obtained by the calculation unit, Control is performed to move the scrap winding shaft in a direction away from the peeling roller.

In addition, in the wound scrap winding apparatus for continuous label paper, which is an aspect of the present invention, it may further include a tension adjusting unit installed on a drive shaft of the scrap winding shaft to adjust the tension applied to the punched scrap.

In addition, in the continuous label paper punched scrap winding device as an aspect of the present invention, a touch roller capable of contacting the outer peripheral surface of the punched scrap wound around the scrap winding shaft to correspond to the change in the diameter of the roll is added. may be provided.

The method for winding the punched scrap of continuous label paper, which is one aspect of the present invention, is a method for winding continuous label paper that has been semi-punched, and separates the punched product and punched scrap adhered to the ground with a peeling roller. a scrap winding process of winding the punched scrap peeled off from the ground on a scrap winding shaft, a roll diameter calculation step of obtaining a roll diameter of the punched scrap wound around the scrap winding shaft, and the roll diameter calculation step When the roll diameter is larger than the preset rising start roll diameter, a scrap winding shaft moving step of moving the scrap winding shaft in a direction away from the peeling roller was provided.

According to the continuous label paper punched scrap winding device according to the present invention, the scrap winding shaft can be moved in a direction away from the peeling roller based on the roll diameter of the punched scrap wound around the scrap winding shaft. Therefore, the distance between the outer peripheral surface of the punched scrap wound around the scrap winding shaft and the outer peripheral surface of the peeling roller can be suppressed to be small (interval includes zero). That is, the size of the scrap path from the outer peripheral surface of the peeling roller to the outer peripheral surface of the punched scrap can be suppressed small.

For this reason, even when the predetermined shape of a punched product is a circular shape other than a rectangle, or an irregular shape, by stabilizing the tension|tensile_strength which generate|occur|produces in the punched scrap during winding|winding, cutting of punched scrap can be prevented as much as possible.

Further, by reducing the size of the scrap path from the outer peripheral surface of the peeling roller to the outer peripheral surface of the punched scrap, cutting of the punched scrap can be suppressed even when strong tension is applied to the punched scrap as compared with the prior art.

Furthermore, by suppressing the cutting of the punched scrap, the speed at which the punched scrap is wound around the scrap winding shaft can be increased. For this reason, the printing speed of continuous label paper can be increased, and productivity of a punched product can be improved significantly.

In addition, by providing a tension adjusting unit on the drive shaft of the scrap winding shaft, the tension applied to the punched scrap by winding can be adjusted and kept constant. For this reason, it can suppress that the punched scrap is cut|disconnected by the tension fluctuation|variation at the time of winding-up, and can wind up the punched scrap in a stable state.

Furthermore, by making the touch roller correspond to the change in the roll diameter, the touch roller can come into contact with the outer peripheral surface of the punched scrap. Therefore, the entire outer peripheral surface of the punched scrap can be flattened with the touch roller. For this reason, the space|interval between the outer peripheral surface of the punched scrap wound up by the scrap winding shaft, and the outer peripheral surface of a peeling roller can be maintained still more preferably. Therefore, the tension|tensile_strength which generate|occur|produces in the punched scrap during winding|winding can be stabilized further favorably.

According to the wound scrap winding method for continuous label paper according to the present invention, in the scrap winding process, the punched scrap is wound on a scrap winding shaft, and the roll diameter of the punched scrap is obtained in the roll diameter calculation process. In addition, in the scrap winding shaft moving step, when the roll diameter obtained in the roll diameter calculation step is larger than a preset rising start roll diameter, the scrap winding shaft is moved in a direction away from the peeling roller.

Therefore, the distance between the outer peripheral surface of the punched scrap wound around the scrap winding shaft and the outer peripheral surface of the peeling roller can be suppressed to be small (interval includes zero). That is, the scrap path dimension from the outer peripheral surface of a peeling roller to the outer peripheral surface of punched scrap can be suppressed small.

For this reason, even when the predetermined shape of a punched product is a circular shape other than a rectangle, or an irregular shape, by stabilizing the tension|tensile_strength which generate|occur|produces in the punched scrap during winding|winding, cutting of punched scrap can be prevented as much as possible.

Further, by reducing the size of the scrap path from the outer peripheral surface of the peeling roller to the outer peripheral surface of the punched scrap, it is possible to suppress cutting of the punched scrap even when strong tension is applied to the punched scrap as compared with the prior art.

Furthermore, by suppressing the cutting of the punched scrap, the speed at which the punched scrap is wound around the scrap winding shaft can be increased. For this reason, the printing speed of continuous label paper can be increased, and productivity of a punched product can be improved significantly.

In the semi-punching process, the label substrate 32 and the adhesive layer of the continuous label paper 30 are processed so that the frame is surrounded in a predetermined shape, and the base 31 is not processed.

After the label 34 is semi-punched on the continuous label paper 30, the scrap 36 is punched from the sheet 31 of the continuous label paper 30 by a fixed peeling roller (peel roller) 47. This is peeled off. That is, by the fixed peeling roller 47, the label substrate 32 of the continuous label sheet 30 is formed into the label 34 adhered to the sheet 31 and the punched scrap 36 peeled from the sheet 31. are separated The label 34 adhered to the sheet 31 is conveyed in the direction indicated by the arrow B. As shown in FIG. On the other hand, the punched scrap 36 peeled off from the ground 31 is attached to the branch pipe 64 of the scrap winding shaft 51 , and is wound up in a roll shape by rotation of the scrap winding shaft 51 .

Hereinafter, the punched scrap 36 wound on the scrap winding shaft 51 in the form of a roll is referred to as a "punching scrap roll 37".

Hereinafter, the configuration of the punched scrap winding device 10 will be described with reference to FIGS. 1 to 10 .

1 and 5, the frame 12 of the punched scrap take-up device 10 includes a winding mechanism 14, a vertical movement mechanism 16, a touch roller mechanism 18, and a detection means 20. This is supported. Moreover, the conveyance roller 41, the nip roller (or nip roller) 42, and guide rollers 43-45 are rotatably supported by the frame 12. As shown in FIG. The conveying roller 41 sandwiches the continuous label sheet 30 together with the nip roller (or nipkoro) 42 to convey it.

Further, a fixed peeling roller 47 is rotatably supported on the frame 12 . In addition to this, an escape hole 48 is formed in the frame 12 . The escape hole 48 extends in the vertical direction so that the scrap winding shaft 51 is movable in the vertical direction.

The winding mechanism 14 includes a scrap winding shaft 51 , a powder clutch (tension adjusting unit) 53 , and a first servo motor 55 . The scrap winding shaft 51 , the powder clutch 53 , and the first servo motor 55 are attached to the movable body 76 of the vertical movement mechanism 16 .

The scrap winding shaft 51 is rotatably supported by the upper part 85a of the 1st table 85 of the movable body 76 through a shaft number. The scrap winding shaft 51 is provided above the roller center 47b of the fixed peeling roller 47 in the vertical direction.

In addition, the scrap winding shaft 51 is formed in a hollow shape having a circular cross-section. A plurality of long holes (slits) 57 extending in the axial direction are formed on the outer periphery of the scrap winding shaft 51 . A first timing pulley 58 is coaxially attached to the scrap winding shaft 51 .

A rubber tube is accommodated in the scrap winding shaft 51 to be elastically deformable. A metal claw (hereinafter referred to as a lug, 62) is provided on the outer periphery of the rubber tube. An air passage communicates with the inside of the rubber tube. The air passage communicates with the air supply source through the rotary joint 63 .

Air supplied from the air supply source is filled in the rubber tube through the rotary joint 63 or the air passage. Thereby, the rubber tube expands radially outward, and the lug 62 protrudes radially outward from the elongate hole 57 of the scrap winding shaft 51. As shown in FIG. Here, a branch pipe 64 (refer to FIG. 2 ) is engaged with the scrap winding shaft 51 . Accordingly, the lug 62 protruding from the long hole 57 of the scrap winding shaft 51 abuts against the inner surface of the paper tube 64 , and the paper tube 64 is fixed coaxially to the scrap winding shaft 51 . .

Although this embodiment demonstrates the example which projects the lug 62 radially outward using air pressure, it is not limited to this. As another example, for example, the lugs 62 may be mechanically protruded outward in the radial direction.

A rotation stop bracket 65 is attached to the case of the rotary joint 63 .

The rotation stop bracket 65 is attached to the second table 86 of the movable body 76 . Accordingly, the accompanying rotation of the case of the rotary joint 63 is suppressed by the rotation stop bracket 65 .

4 to 6 , a first servo motor 55 is connected to the scrap winding shaft 51 through a powder clutch 53 . The first servo motor 55 is attached to the plate 83 under the second table 86 . A plate 83 is attached to the bottom of the second table 86 .

Specifically, it is formed so that the some 1st long hole 86a may extend in the up-down direction in the 2nd table 86 lower part. The plate 83 is attached to the lower part of the second table 86 by the first bolt 81 penetrating the plurality of first long holes 86a. The first servo motor 55 is attached to the lower part of the second table 86 of the movable body 76 through a plate 83 .

Accordingly, by loosening the first bolt 81 and moving the plate 83 in the vertical direction, the first servo motor 55 can be moved in the vertical direction. That is, the first servo motor 55 may be positioned in the vertical direction with respect to the powder clutch 53 .

A second timing pulley 66 is coaxially attached to the output shaft of the first servo motor 55 .

In the second table 86 , a powder clutch 53 is disposed between the first servo motor 55 and the scrap winding shaft 51 . Here, a plurality of second long holes 86b are formed in the upper portion of the second table 86 so as to extend in the vertical direction. The second bolt 97 is configured to pass through the plurality of second long holes 86b and to be screw-coupled to the pair of connecting members 87 . The second table 86 can be fixed by tightening the second bolt 97 .

Accordingly, by loosening the second bolt 97 and moving the second table 86 in the vertical direction, the powder clutch 53 can be moved in the vertical direction. That is, the powder clutch 53 can be positioned in the vertical direction with respect to the scrap winding shaft 51 .

The powder clutch 53 is installed on the drive shaft of the scrap winding shaft 51 . The powder clutch 53 is generally used, for example, in production of a long film. The powder clutch 53 uses powder (magnetic iron powder) to transmit torque, and has the smoothness of a fluid clutch and the high-efficiency connectivity of a friction plate clutch.

That is, by making the powder clutch 53 slide smoothly, the fluctuation of the tension applied to the punched scrap 36 can be kept constant. In addition, the set torque of the powder clutch 53 can be changed in stages according to the roll diameter D of the punching scrap roll 37 (refer to FIG. 2). Therefore, by providing the powder clutch 53 on the drive shaft of the scrap winding shaft 51, the tension applied to the punching scrap 36 of the punching scrap roll 37 can be adjusted, and the fluctuation of the tension can be kept constant.

For this reason, it is possible to prevent the punched scrap 36 from being cut due to a change in tension applied to the punched scrap 36 .

2 and 3, in the present embodiment, the number of rotations of the scrap winding shaft 51 is the minimum when the roll diameter D of the punched scrap roll 37 is the minimum (that is, the roll diameter D is the paper tube ( 64)), the winding amount of the punched scrap 36 is set to be at least equal to the conveying amount of the continuous label paper 30 in the conveying path, or a constant value greater than the conveying amount.

Accordingly, the punched scrap 36 is continuously wound around the scrap winding shaft 51 . On the other hand, as the roll diameter D of the punched scrap roll 37 increases, the amount of winding of the punched scrap 36 on the scrap winding shaft 51 increases with respect to the amount of continuous label paper 30 conveyed along the conveying path. In this case, since the tension applied to the punching scrap 36 is increased, the set torque of the powder clutch 53 (refer to FIG. 6) is adjusted step by step accordingly.

As shown in FIG. 2, FIG. 5, the tension|tensile_strength is provided to the punched scrap 36 of the punched scrap roll 37. As shown in FIG.

The tension changes by affecting the change in the roll diameter D of the punched scrap roll 37 or the mechanical loss of the mechanical system, or the torque fluctuation during acceleration/deceleration of the first servomotor 55 . Accordingly, by interposing the powder clutch 53 between the scrap take-up shaft 51 and the first servo motor 55 , it is possible to maintain a constant variation in the tension applied to the punched scrap 36 .

In addition, the powder clutch 53 has a structure in which the set torque can be changed in stages according to the roll diameter D of the punched scrap roll 37 in order to respond to the fluctuation of the roll diameter D of the punched scrap roll 37 . That is, the tension applied to the punched scrap 36 varies according to the change in the roll diameter D of the punched scrap roll 37 as long as the torque of the scrap winding shaft 51 is constant. Therefore, by changing the set torque of the powder clutch 53 in stages according to the roll diameter D of the punching scrap roll 37, the fluctuation of the tension can be kept constant.

In this way, by providing the powder clutch 53 on the drive shaft of the scrap winding shaft 51, the tension applied to the punched scrap 36 by winding can be constantly maintained. Thereby, it is suppressed that the punched scrap 36 is cut|disconnected by the tension fluctuation|variation at the time of winding-up, and the punched scrap 36 can be wound up in a stable state.

The set torque of the powder clutch 53 may be changed on a monitor screen installed in the punched scrap winding device 10 .

In addition, a fourth timing pulley 69 is coaxially attached to the output shaft of the powder clutch 53 .

The second timing pulley 66 of the first servo motor 55 is connected to the third timing pulley 68 of the powder clutch 53 through a first timing belt 71 . The tension of the first timing belt 71 is preferably adjusted by loosening the plurality of first bolts 81 (refer to Fig. 4) to move the first servo motor 55 in the vertical direction.

Further, the fourth timing pulley 69 of the powder clutch 53 is connected to the first timing pulley 58 of the scrap winding shaft 51 through the second timing belt 72 . The tension of the second timing belt 72 is preferably adjusted by loosening the plurality of second bolts 97 (refer to Fig. 4) and moving the powder clutch 53 in the vertical direction.

In this state, by rotating the second timing pulley 66 with the first servo motor 55 , the rotation of the second timing pulley is transmitted through the first timing belt 71 to the third timing pulley of the powder clutch 53 . (68). As the third timing pulley 68 rotates, the input shaft of the powder clutch 53 rotates.

When the input shaft of the powder clutch 53 rotates, the output shaft of the powder clutch 53 rotates. As the output shaft of the powder clutch 53 rotates, the fourth timing pulley 69 rotates. Rotation of the fourth timing pulley 69 is transmitted to the first timing pulley 58 via the second timing belt 72 . As the first timing pulley 58 rotates, the scrap winding shaft 51 rotates in the winding direction of the punched scrap 36 . Thereby, the punched scrap 36 is wound around the branch pipe 64 of the scrap winding shaft 51 .

Here, the fourth timing pulley 69 and the first timing pulley 58 are formed with the same number of teeth. Accordingly, the rotation speed of the scrap winding shaft 51 is equal to the rotation speed of the output shaft of the powder clutch 53 . In addition, the second timing pulley 66 of the output shaft of the first servo motor 55 and the third timing pulley 68 of the input shaft of the powder clutch 53 are connected to the fourth timing pulley ( 69) and the same number of teeth.

In this way, by interposing the powder clutch 53 between the scrap winding shaft 51 and the first servo motor 55 , the fluctuation of the tension applied to the punched scrap 36 can be constantly maintained by the powder clutch 53 . have.

In addition, the tension applied to the punched scrap 36 fluctuates according to the change in the roll diameter D of the punched scrap roll 37 when the torque of the scrap winding shaft 51 is kept constant. In order to respond to the fluctuation of the roll diameter D, the set torque of the powder clutch 53 can be changed in stages according to the roll diameter D of the punching scrap roll 37 .

Thereby, it is possible to prevent the punched scrap 36 from being cut due to a change in tension applied to the punched scrap 36 .

The connection of the 1st servo motor 55, the powder clutch 53, and the scrap take-up shaft 51 is not limited to the structure of this embodiment. The scrap winding shaft 51 and the first servo motor 55 may be connected via the powder clutch 53 .

5 and 7, by moving the scrap winding shaft 51 in the vertical direction (arrow C direction) with the vertical movement mechanism 16, the change in the roll diameter D of the punched scrap roll 37 is responded to. to move the scrap winding shaft 51 in the vertical direction. That is, the scrap winding shaft 51 can be moved by the vertical movement mechanism 16 in a direction away from the fixed peeling roller 47 or in a direction close to the stationary peeling roller 47 .

As a result, the outer peripheral surface 36a of the punched scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 are close enough to not come into contact with each other, or the outer peripheral surface 36a of the punched scrap roll 37 and the fixed peeling The scrap winding shaft 51 can be adjusted to a so-called kiss-touch position where the outer peripheral surface 47a of the roller 47 slightly contacts.

A touch roller mechanism 18 (refer to FIG. 6 ) is provided above the vertical movement mechanism 16 and the winding mechanism 14 .

8 and 9 , the touch roller mechanism 18 includes a rotary actuator 101 , an arm 102 , a touch roller 103 , and a load block 104 . In addition, in FIG. 9, in order to make understanding about the structure of the touch roller mechanism 18 easy, for convenience, the touch roller 103 is shown in the state arrange|positioned upward.

The rotary actuator 101 is attached to the upper end 12a of the frame 12 via a support bracket 106 . A central portion (hereinafter, referred to as an arm central portion) 102a of the arm 102 is attached to the rotation support shaft 107 of the rotary actuator 101 .

Accordingly, the arm 102 is pressed in the direction of the arrow E by the pressing force of the rotary actuator 101 . A touch roller 103 is attached to one end 102b of the arm 102 .

That is, the touch roller mechanism 18 is a swing type touch roller attached to the rotation support shaft 107 of the rotary actuator 101 .

The touch roller 103 includes a roller shaft 108 attached to one end 102b of the arm 102 , and a roller body 112 supported on the roller shaft 108 . The roller shaft 108 has a base end 108a attached to one end 102b of the arm 102 . The roller shaft 108 extends in a direction intersecting (specifically orthogonal) with respect to the arm 102 . The roller body 112 is coaxially and rotatably attached to the roller shaft 108 via a shaft number 109 .

A load block 104 is attached to the other end 102c of the arm 102 . The load block 104 is movably supported along the arm 102 by loosening the adjustment bolt 114 . Accordingly, the attachment position of the load block 104 can be adjusted.

By attaching the load block 104 to the other end 102c of the arm 102 , a balance with the pressing force of the rotary actuator 101 is maintained. Therefore, the contact force with respect to the outer peripheral surface 36a of the punching scrap roll 37 by the touch roller 103 (that is, the roller main body 112) can be adjusted preferably.

In addition, the arm 102 is supported pivotally about the rotation support shaft 107 . Therefore, it is possible to move the touch roller 103 corresponding to the roll diameter D of the punching scrap roll 37 . That is, it can be made to correspond to the roll diameter D of the punched scrap roll 37, and can make contact with the outer peripheral surface 36a of the punched scrap roll 37. As shown in FIG.

Here, the rotation support shaft 107 of the rotary actuator 101 so that the touch roller 103 can pivot up to the turning angle of the arm 102 when the roll diameter D of the punched scrap roll 37 becomes the maximum diameter. rotation angle is set.

The touch roller 103 can adjust the air pressure with a regulator installed in the air pipe path. For example, by adjusting the air pressure of the regulator to 0.0 to 0.1 MPa, the contact pressure of the touch roller 103 is made to correspond to conditions such as the type of continuous label paper 30 (refer to FIG. 3 ) and the punching area. It can be changed arbitrarily.

That is, the touch roller 103 is adjusted so as to contact the outer peripheral surface 36a of the punched scrap roll 37 with a slight pressure to prevent vibration from occurring. By applying a slight pressure to prevent vibration from occurring on the outer peripheral surface 36a of the punched scrap roll 37, the winding collapse of the punched scrap 36 being wound on the scrap winding shaft 51, or the wound punched scrap 36 ) to prevent excess air from being drawn between floors. That is, the roll shape of the punched scrap roll 37 can be preferably corrected by the touch roller 103 .

By correcting (correcting) the roll shape of the punching scrap roll 37 with the touch roller 103, the unevenness of the outer peripheral surface 36a of the punching scrap roll 37 can be uniformed to some extent. For this reason, the fluctuation|variation of the tension|tensile_strength resulting from the unevenness|corrugation of the outer peripheral surface 36a of the punching scrap roll 37 can be suppressed to some extent.

Moreover, the unevenness|corrugation of the outer peripheral surface 36a of the punching scrap roll 37 is equalized. Thereby, even when the outer peripheral surface 36a of the punching scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 are in contact, the unevenness of the outer peripheral surface 36a of the punching scrap roll 37 and the fixed peeling roller 47 ) of the outer peripheral surface (47a) press-contact can be prevented from occurring.

In this way, the touch roller 103 was made to correspond to the change in the roll diameter D of the punching scrap roll 37, so that the touch roller 103 could come into contact with the outer peripheral surface 36a of the punching scrap roll 37. Therefore, the entire outer peripheral surface 36a of the punching scrap roll 37 can be made flat and uniform with the touch roller 103 . For this reason, the space|interval r of the outer peripheral surface 36a of the punching scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 can be maintained preferably. Accordingly, the tension generated in the punched scrap 36 being wound around the scrap winding shaft 51 can be satisfactorily stabilized.

Here, when the touch roller 103 is not used, a turning fixing part 105 for fixing the touch roller 103 to the frame 12 so as not to turn it is provided. The pivot fixing part 105 has a fixing pin 123 and a chain 124 . A fixing pin 123 is connected to the frame 12 via a chain 124 . In addition, an attachment hole 102d is formed at one end 102b side of the arm 102 . When the touch roller 103 is not used, the fixing pin 123 is inserted into the attachment hole 102d. For this reason, the chain 124 is pulled, resists the pressing force of the rotary actuator 101, and it can be fixed to the frame 12 so that the touch roller 103 may not turn.

In addition, although the example which used the rotary actuator 101 as a turning means of the arm 102 was demonstrated in this embodiment, it is not limited to this. As another example, for example, a rubber damper may be used.

4 and 6, the detection means 20 includes a first sensor 116, a second sensor 117, a third sensor (second detection unit, 118), and a line encoder (first detection unit). , 119) (see FIG. 8).

The first sensor 116 is attached to the upper portion 12b of the frame 12 through a first attachment bracket 127 . The first sensor 116 detects the detection piece 128 . The detection piece 128 is attached to the side surface 85b end 85c of the 1st table 85. As shown in FIG. When the 1st sensor 116 detects the detection piece 128, the upper limit of the 1st table 85 (namely, the movable body 76) which moves in an up-down direction is determined.

The second sensor 117 is attached to the portion 12c closer to the lower portion than the upper portion 12b of the frame 12 through the second bracket 129 . The second sensor 117 detects the detection piece 128 . When the 2nd sensor 117 detects the detection piece 128, the lower limit of the 1st table 85 (namely, the movable body 76) which moves in an up-down direction is determined.

Here, the attachment position or detection position of the first sensor 116 and the second sensor 117 , and the number of the first sensor 116 and the second sensor 117 are not limited to the embodiment. For example, you may attach the 1st sensor 116 and the 2nd sensor 117 from the front side of the 1st table 85. As shown in FIG. In addition, a long hole may be formed in the front surface of the slider 84 with a length of the maximum movement amount + alpha , and one sensor may be provided on the front side of the slider 84 . Furthermore, the side surface 85b of the 1st table 85 may be peeled off step by step in an up-down direction, a convex state may be made into movement amount +(alpha), and it may determine with the sensor provided in one place.

The third sensor 118 is attached to the output shaft side bracket 121 of the powder clutch 53 . Specifically, the plate 122 is attached to the output shaft side of the powder clutch 53 . One end 121a of the bracket 121 is attached to the lower end of the plate 122 . A third sensor 118 is attached to the other end 121b of the bracket 121 .

In addition, the rotating body 132 is provided on the same shaft as the fourth timing pulley 69 of the output shaft of the powder clutch 53 , and the detection piece 133 is provided on the outer periphery of the rotating body 132 .

Here, the fourth timing pulley 69 of the output shaft of the powder clutch 53 and the first timing pulley 58 of the scrap winding shaft 51 are formed with the same number of teeth. That is, the rotation speed of the rotating body 132 (ie, the detection piece 133 ) is equal to the rotation speed of the scrap winding shaft 51 . Accordingly, one rotation of the scrap winding shaft 51 is detected by detecting the detection piece 133 with the third sensor 118 .

Hereinafter, a pulse signal indicating the number of rotations of the scrap winding shaft 51 is referred to as a "winding pulse".

Here, the attachment position of the 3rd sensor 118 and the detection piece 133 is not limited to the example of this embodiment. As another attachment position, for example, the third sensor 118 and the detection piece 133 may be attached to a position that is a rotational point similar to that of the scrap winding shaft 51 on the motor side of the frame 12 . The third sensor 118 and the detection piece 133 may be attached to a position where a pulse is transmitted once from the third sensor 118 every time the scrap winding shaft 51 rotates once.

1 and 10, a third servo motor (not shown) for conveying the continuous label sheet 30 in the conveying path of the continuous label sheet 30, a conveying roller 41, and a nip roller (or nipkoro) 42 and guide rollers 43 to 45 are provided. A line encoder 119 is provided in addition to the third servo motor.

The line encoder 119 is a rotary encoder connected to the conveyance path of the continuous label sheet 30 (specifically, the conveyance roller 41). The line encoder 119 transmits a pulse signal corresponding to the conveyed amount of the continuous label sheet 30 . That is, the line encoder 119 detects the conveyance amount of the continuous label sheet 30 . Hereinafter, a pulse signal corresponding to the amount of conveyance is referred to as a "carriage pulse".

Here, the roll diameter of the punched scrap roll 37 is determined from the conveyed amount of the continuous label paper 30 by detecting the conveying pulse of the line encoder 119 with respect to the winding pulse when the scrap winding shaft 51 rotates once. D can be obtained by arithmetic.

In addition, the positions of the conveyance roller 41, the nip roller (or nip roller) 42, the guide rollers 43-45, and the line encoder 119 are not limited to the position of drawing.

The roll diameter D of the punched scrap roll 37 is calculated|required by the calculating part 22 based on the winding pulse and conveyance pulse amounts. That is, the calculating unit 22 calculates the amount of the punching scrap roll 37 from the conveying pulse amount of the line encoder 119 with respect to the winding pulse transmitted from the third sensor 118 every time the scrap winding shaft 51 rotates once. The roll diameter D can be obtained.

Next, the method of calculating|requiring the roll diameter D of the punching scrap roll 37 by the calculating part 22 is demonstrated based on FIG.

As shown in FIG. 10, the roll diameter of the punched scrap roll 37 is D, and the feed amount of the continuous label paper 30 when the scrap winding shaft 51 rotates once (that is, the wound punched scrap 36). Let L be the circumference of

D=L/π ...(1)

On the other hand, in the conveyance path of the continuous label paper 30, the first conveyance roller 41 and the line encoder 119 of the roll diameter d are provided.

Let n be the number of conveyance pulses which the line encoder 119 transmits with respect to 1 rotation of the 1st conveyance roller 41. As shown in FIG. When the continuous label sheet 30 is conveyed by a distance ?d, a conveying pulse is transmitted from the line encoder 119 by n pulses. Accordingly, the feed amount of the continuous label sheet 30 per one conveying pulse transmitted by the line encoder 119 is ?d/n.

Here, if the number of transmission pulses of the conveyance pulses of the line encoder 119 when the scrap winding shaft 51 rotates once is N,

L=πdN/n ...(2)

becomes

By substituting equation (2) into equation (1),

D=dN/n ...(3)

can get

The roll diameter d and the number of conveying pulses n of the line encoder 119 are known values. For this reason, the roll diameter D of the punching scrap roll 37 can be calculated|required from the conveyance pulse number N which the line encoder 119 transmits.

Next, an example in which the scrap winding shaft 51 is raised by the control unit 24 will be described with reference to FIGS. 3, 11 and 12 .

As shown in Fig. 3, the peeled punched scrap 36 is in the state of an empty hole through which the label 34 is removed. For this reason, when the tension|tensile_strength given to the punched scrap 36 fluctuates at the time of the scrap winding to the scrap winding-up shaft 51, it is easy to cut|disconnect. Here, the label 34 is not limited to a single quadrilateral. In particular, when the predetermined shape of the label 34 is a circular or irregular shape other than a rectangle, if the tension of the punched scrap 36 fluctuates, the punched scrap 36 is easily cut. In addition, in Fig. 3, in order to facilitate the understanding of the structure, the label 34 is described as a rectangle for convenience.

For example, when the scrap path of the punched scrap 36 of the label 34 is long, the amount of shrinkage in the width direction of the punched scrap 36 increases and the load is concentrated, or the roll diameter of the punched scrap roll 37 decreases. It becomes large and becomes easy to cut at the location where the tension|tensile_strength given to the punched scrap 36 becomes high.

Here, the scrap path refers to a section from when the punched scrap 36 is peeled off from the base 31 until it reaches the scrap winding shaft 51 .

On the other hand, it is conceivable that the outer peripheral surface 36a of the punching scrap roll 37 is maintained in a state in which it is in pressure contact with the outer peripheral surface 47a of the fixed peeling roller 47 . In this state, the difference in the roll diameter D occurs depending on the location of the punched scrap 36 of the punched scrap roll 37 due to uneven winding such as the uneven shape of the outer peripheral surface 36a of the punched scrap roll 37. can think In addition, it is conceivable that the punched scrap roll 37 is eccentrically wound with respect to the paper tube 64, or vibration is generated. As a result, the tension applied to the punched scrap 36 fluctuates, and there is a possibility that the punched scrap 36 is cut.

In view of the above, it is preferable that the position of the scrap winding shaft 51 is at a position where the scrap path is usually a short distance and the winding unevenness does not occur. Therefore, in the punched scrap winding device 10 of this embodiment, the position of the scrap winding shaft 51 is that the outer peripheral surface 36a of the punched scrap roll 37 is in contact with the outer peripheral surface 47a of the fixed peeling roller 47 It is determined at the same location as close enough not to do so. Alternatively, the position of the scrap winding shaft 51 at a position where the outer circumferential surface 36a of the punched scrap roll 37 and the outer circumferential surface 47a of the fixed peeling roller 47 slightly contact, such as a so-called kiss touch, position. is decided

Here, as tension is applied to the punched scrap 36, the punched scrap 36 contracts in the width direction.

For example, when the punched scrap 36 is left out in a grid shape, the punched scrap 36 has a conveying direction belt-shaped portion 361 and a width direction belt-shaped portion 362 . The belt-shaped portion 361 in the conveying direction of the punched scrap 36 is wound on the scrap winding shaft 51 in a state in which it extends in the conveying direction by tension and contracted in the width direction. In this case, the width direction band-shaped portion 362 of the grid-shaped punched scrap 36 is wound on the scrap winding shaft 51 in a state of being stretched and lifted with respect to the conveying direction belt-shaped portion 361 without tension. .

For this reason, the roll diameter D (refer FIG. 2) of the width direction strip|belt-shaped part 362 of the punching scrap roll 37 becomes larger than the roll diameter D of the conveyance direction strip|belt-shaped part 361. FIG. Therefore, the roll diameter D of the band-shaped portion 362 in the width direction of the punched scrap roll 37 and the roll diameter D of the belt-shaped portion 361 in the conveying direction of the punched scrap roll 37 are the same diameter as the touch roller ( 103) (refer to FIG. 2) is provided.

For this reason, the scrap winding shaft 51 is positioned such that the outer peripheral surface 36a of the punched scrap roll 37 is close to the fixed release roller 47 to such an extent that it does not contact the outer peripheral surface 47a of the fixed release roller 47. position can be determined. Alternatively, at a position where the outer circumferential surface 36a of the punched scrap roll 37 and the outer circumferential surface 47a of the fixed peeling roller 47 slightly contact, a position such as a so-called kiss touch, the scrap winding shaft 51 is location can be determined.

As shown in Fig. 11, the interval r between the outer peripheral surface 36a of the punched scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 is usually set to be in the range of 0.0 to 5.0 mm. . However, depending on the roll shape of the punching scrap roll 37, it is also possible to change the setting of the spacing r, and to set the spacing r to 5.0 mm or more. The initial position of the scrap winding shaft 51 is the position shown in the state (A) of FIG. The initial position of the scrap winding shaft 51 is the position of the scrap winding shaft 51 in a state where the punched scrap 36 of the label 34 is not wound on the paper tube 64 fixed to the scrap winding shaft 51 . say

3, the gap r (refer to FIG. 11) is such that the outer circumferential surface 64a of the paper tube 64 fixed to the scrap winding shaft 51 is not in contact with the outer circumferential surface 47a of the fixed peeling roller 47. It is set at the same distance as close to the fixed peeling roller 47 to such an extent that it is not possible. Accordingly, when the punched scrap 36 is peeled off from the base 31 by the fixed peeling roller 47 , it is immediately wound around the paper tube 64 fixed to the scrap winding shaft 51 . The wound scrap 36 is integrated with the scrap winding shaft 51 (that is, the paper tube 64 ) by the adhesive surface of the punch scrap 36 .

For this reason, the distance of the scrap path|pass of the punched scrap 36 conveyed by a single body is suppressed short, and the punched scrap 36 is wound up without being cut|disconnected.

Hereinafter, a method for winding the punched scrap of continuous label paper for suppressing the distance of the scrap path of the punched scrap 36 conveyed as a group to be short will be described with reference to FIG. 11 .

As shown in the state (A) of FIGS. 2 and 11 , first, the axial position P of the scrap winding shaft 51 is set to the outer circumferential surface 64a of the paper tube 64 and the outer circumferential surface 47a of the fixed peeling roller 47 . is set so that the distance r is close enough that the outer circumferential surface 64a and the outer circumferential surface 47a do not come into contact (specifically, the interval r is usually set in the range of 0.0 to 5.0 mm). In addition, the axial position P indicates the distance between the outer peripheral surface 47a of the fixed peeling roller 47 and the center 51a of the scrap winding shaft 51 .

As shown in the state (B) of FIGS. 2 and 11 , when conveying of the continuous label paper 30 is started, in the scrap winding process, the scrap winding shaft 51 rotates. As the scrap winding shaft 51 rotates, the punched scrap 36 peeled off from the base 31 (refer to FIG. 3 ) is wound around the branch pipe 64 of the scrap winding shaft 51 .

In the roll diameter calculation step, the roll diameter D of the punched scrap roll 37 is determined based on the winding pulse signal from the third sensor 118 (refer to FIG. 1 ) and the conveying pulse signal from the line encoder 119 . save The third sensor 118 detects one rotation of the scrap winding shaft 51 . The line encoder 119 detects the conveyance amount of the continuous label sheet 30 .

Next, the calculated roll diameter D is memorize|stored in the calculating part 22 in the controller 21. A roll diameter obtained by adding the increment of an arbitrarily set radial dimension to the roll diameter D stored in the calculation unit 22 is set in advance to the "rise start roll diameter D1" of the punching scrap roll 37 .

As shown in state (C) of FIGS. 2 and 11 , during conveyance of the continuous label paper 30, the amount of conveying pulses of the line encoder 119 cut out every time the scrap winding shaft 51 rotates once. The roll diameter D of the punched scrap roll 37 is calculated each time from

In the scrap winding shaft moving step, the obtained roll diameter D of the punched scrap roll 37 is compared with the "rising start diameter D1". When the compared roll diameter D is larger than the "rising start roll diameter D1", based on the signal from the control part 24, the 2nd servomotor 82 (refer FIG. 1) of the vertical movement mechanism 16 is driven. .

By rotating the sixth timing pulley 95 with the second servo motor 82 , the rotation of the sixth timing pulley is transmitted to the fifth timing pulley 93 of the rotating shaft 89 via the third timing belt 96 . . As the fifth timing pulley 93 rotates, the pair of drive gears 79 rotate via the rotation shaft 89 .

As the pair of driving gears 79 rotate, the pair of driven gears 78 rotate.

As the pair of driven gears 78 rotate, the pair of ball screws 77 rotate. When the pair of ball screws 77 rotate, the connecting bracket 92 (that is, the movable body 76) moves in the vertical direction.

A winding mechanism 14 is attached to the first table 85 and the second table 86 of the movable body 76 . When the movable body 76 moves in the vertical direction, the scrap winding shaft 51 is raised to the axial position P by the set value for raising the scrap winding shaft of the scrap winding shaft 51 arbitrarily set. That is, the scrap winding shaft 51 is moved in a direction away from the fixed peeling roller 47 .

For this reason, as shown in the state (C) of FIG. 11, the distance r between the outer peripheral surface 36a of the punched scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 is equal to the distance r of the punched scrap roll 37 ) is a distance close to the fixed release roller 47 to such an extent that the outer peripheral surface 36a of the fixed release roller 47 does not come into contact with the outer peripheral surface 47a of the fixed release roller 47 .

After completion of the lifting operation of the scrap winding shaft 51 , the roll diameter D of the punching scrap roll 37 is calculated again in the same manner. By overwriting the roll diameter D on the calculation unit 22 , a new “rising start roll diameter D1” of the scrap winding shaft 51 is determined. In the following, similarly, the scrap winding shaft 51 is raised based on a signal from the control unit 24 .

That is, the control unit 24 moves the scrap winding shaft 51 away from the fixed release roller 47 or in a direction close to the fixed release roller 47 based on the roll diameter D obtained by the calculating unit 22 . The vertical movement mechanism 16 is controlled so that

Next, an example in which the scrap winding shaft 51 is moved in a direction away from the fixed peeling roller 47 by the control unit 24 will be described in detail with reference to FIGS. 11 and 12 .

The state (A), the state (B), and the state (C) of FIG. 11 are the scrap winding shaft 51, the punched scrap roll 37, and the fixed peeling roller 47 at the time points A, B, and C of FIG. 12 . It is a front view showing the positional relationship of 12 is a graph showing an example of the rising timing of the scrap winding shaft 51 in the case of executing the winding operation of the punched scrap.

11, the distance r is the distance between the outer peripheral surface 36a of the punched scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47, or the outer peripheral surface 64a of the paper tube 64 and the fixed peeling roller 47 The distance of the outer peripheral surface 47a of (47) is shown. In addition, as described above, the axial position P represents the distance between the outer peripheral surface 47a of the fixed peeling roller 47 and the center 51a of the scrap winding shaft 51 .

As shown in the state (A) of Fig. 11 and Fig. 12, when the scrap winding shaft 51 rotates at the rotation speed A (A = 0), the tube diameter of the paper tube 64 is smaller than the rising start roll diameter D1. formed small. For example, the branch pipe 64 is set to a pipe diameter of 100 mm. Accordingly, a gap r is maintained between the outer circumferential surface 64a of the paper tube 64 and the outer circumferential surface 47a of the fixed peeling roller 47 . For this reason, in a state in which the scrap winding shaft 51 does not rise, the punched scrap 36 is wound around the branch pipe 64 of the scrap winding shaft 51 .

As shown in the state (B) of FIG. 11 and FIG. 12 , when the punched scrap 36 is wound around the branch pipe 64 of the scrap winding shaft 51 , the roll diameter D of the punched scrap roll 37 becomes large. At the same time, the distance r between the outer peripheral surface 36a of the punching scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 becomes small.

In the state in which the scrap winding shaft 51 has reached the rotation speed B, the roll diameter D of the punching scrap roll 37 exceeds the "rising start roll diameter D1".

The scrap winding shaft 51 starts to rise. While the scrap winding shaft 51 is rising, the punched scrap 36 is continuously wound around the scrap winding shaft 51 . As the punched scrap 36 continues to be wound around the paper tube 64 of the scrap winding shaft 51 , the roll diameter D of the punched scrap roll 37 becomes large. In this state, the scrap winding shaft 51 is raised. Accordingly, the interval r between the outer circumferential surface 36a of the punched scrap roll 37 and the outer circumferential surface 47a of the fixed peeling roller 47 increases toward the preset scrap take-up shaft rise setting value.

As shown in the state (C) of FIG. 11 , as shown in FIG. 12 , when the scrap take-up shaft 51 rotates at the rotational speed C, the rise value of the scrap take-up shaft 51 is a preset scrap take-up shaft rise set value. (eg 5.0 mm). Accordingly, the scrap winding shaft 51 stops rising. A roll diameter obtained by adding an arbitrarily set increase in the radial dimension (for example, 3.0 mm) to the roll diameter D when the scrap winding shaft 51 stops rising is determined as the new rising start roll diameter D1. Thus, the punched scrap 36 is wound up without raising the scrap winding shaft 51 until the roll diameter D reaches the rising start roll diameter D1.

As described above. By sequentially repeating the operations of states (A) to (C), the interval r between the outer peripheral surface 36a of the punched scrap roll 37 and the outer peripheral surface 47a of the fixed peeling roller 47 is usually 0.0≤r≤5.0 It is set in the range of mm.

Therefore, the position as close to or slightly in contact with the fixed peeling roller 47 to such an extent that the outer circumferential surface 36a of the punching scrap roll 37 does not contact the outer circumferential surface 47a of the fixed peeling roller 47 can be maintained. have. For this reason, the stabilizing winding of the punching scrap 36 can be maintained without the punched scrap 36 being cut|disconnected.

In this way, based on the roll diameter D of the punched scrap roll 37 , the scrap winding shaft 51 can be moved in a direction away from the fixed release roller 47 or in a direction close to the fixed release roller 47 . . Therefore, the space|interval r of the outer peripheral surface 36a of the punching scrap roll 37 and the outer peripheral surface 47a of the stationary peeling roller 47 can be suppressed small (interval r also includes zero). That is, the scrap path dimension from the outer peripheral surface 47a of the fixed peeling roller 47 to the outer peripheral surface 36a of the punching scrap roll 37 can be suppressed small.

For this reason, even when the predetermined shape of the label 34 is a circle or an irregular shape other than a rectangle, it is possible to prevent the punched scrap 36 from being cut as much as possible by stabilizing the tension generated in the punched scrap 36 during winding. have.

In addition, by suppressing the scrap path size from the outer circumferential surface 47a of the fixed peeling roller 47 to the outer circumferential surface 36a of the punched scrap roll 37 to be small, as compared with the prior art, strong tension in the punched scrap 36 is increased. Even if it provides, it can suppress that the punched scrap 36 is cut|disconnected.

Furthermore, by suppressing the cutting of the punched scrap 36 , the printing speed of the continuous label paper 30 can be increased. As a result, the productivity of the label 34 can be greatly improved.

In addition, in this embodiment, although the increment of the radial dimension is set to 3.0 mm and the set value for raising the scrap winding shaft is set to 5.0 mm, the increase in the radial dimension and the set value for the rise of the scrap winding shaft are limited to 3.0 mm or 5.0 mm not. That is, the outer circumferential surface 64a of the paper tube 64 fixed to the scrap winding shaft 51 by the lugs 62, or the outer circumferential surface 36a of the punched scrap roll 37 and the outer circumferential surface 47a of the fixed peeling roller 47 What is necessary is just control in which the scrap winding shaft 51 rises so that the space|interval r may maintain a fixed range.

As another example, for example, the thickness dimension of the continuous label paper 30 may be measured before the start of winding, and the setting value for raising the scrap winding shaft may be changed according to the value. In addition, the value may be changed according to the type of the continuous label sheet 30 or the winding speed.

Further, in addition to the automatic operation during operation as described in the present embodiment, the vertical movement mechanism 16 of the scrap winding shaft 51 manually moves the scrap winding shaft 51 up and down while the winding operation is stopped, for example. It is also possible to make it work. Manual operation of the scrap take-up shaft 51 is used, for example, when the punched scrap roll 37 has reached the maximum roll diameter, and the punched scrap roll is removed from the scrap take-up shaft 51 .

It is not limited to the form. As another example, for example, instead of the pair of ball screws 77, it is also possible to use a trapezoidal screw or the like. Moreover, although it is preferable to provide the number of the ball screw 77 and trapezoidal screw from points, such as positioning accuracy and durability, it is good also as one.

In addition, in the above embodiment, the powder clutch 53 is exemplified as the tension adjusting unit, and the fluctuation of the tension applied to the punched scrap 36 of the punched scrap roll 37 with the powder clutch 53 is kept constant. has been described, but is not limited thereto. As the other tension adjusting unit, it is also possible to adopt another clutch or the like that slides smoothly and has a function of changing the set torque in stages.

In addition, in the above embodiment, the rotary encoder is described as an example as the line encoder 119 of the first detection unit for detecting the conveyed amount of the continuous label sheet 30, but the present invention is not limited thereto.

In addition, in the said embodiment, although the example which moves the scrap winding shaft 51 by the control part 24 based on the roll diameter D calculated|required by the calculating part 22 was demonstrated, it is not limited to this. As another example, it is also possible to move the scrap winding shaft 51 manually based on the roll diameter D calculated|required by the calculating part 22, for example.

In addition, although the fixed peeling roller 47 was illustrated as a peeling roller in the said embodiment, it is not limited to this. As another example, it is also possible to use the peeling roller as a movable peeling roller, for example.

In addition, in the said embodiment, although the example which provided the scrap winding-up shaft 51 with respect to the roller center 47b of the fixed peeling roller 47 perpendicularly upper side was demonstrated, it is not limited to this. As another example, it is also possible to provide the scrap winding shaft 51 in other directions, such as a diagonally upper side of the stationary peeling roller 47, a lateral side of the stationary peeling roller 47, etc., for example.
